. Referring to the drawing by reference numerals, 1, 1 designate anykind of wheeled or not wheeled supports upon which the frame or body ofthe machine rests at an elevation allowing all its mechanism to workfreely above the ground. Said body consists of a horizontally elongatedbox 2 having depending portion 9 at one end, and in theother or frontend is journaled the main crank shalt 3, operating by a pit-inane aplunger 5, which moves below the bottom opening 6 of a hopper 7 mountedupon the main frame and thus forms the bales in the'baling chamber S, inwhich the bales are bound by twine and then pushed upon a pair of hingedshelves or leaves 102, which automatically drop the bales from theposition 11 to the position. 1 (see Fig. in the depending portion 9 ofthe frame, upon endless chains operated by small sprocket wheels 123,fixed on shaft 124,

whose crank engages in. the slot" 3? of the arm;

the lower liar 36 of said arm is 'yieldingl;

held by the bolts SS-and springs 39 so that the packer will make smallerand smaller ster than the plunger can remove the material.

On tlie'main crank shaft 3 is fixed a 303?.

paratively large gear-wheel 40, turned h" apinion ll, sliding on aleather-keyedv shaft 42, journaled in 'a bracket shi il, and ro tated bya pulley and belt -l6;'the latter may be driven by any suitable sourceof power. Near one end of the pinion 41 is an annular groove 4.7, inwhich engages one or more pins 48 of a lever 49, fuloruined at 50 to abracket 51, and held by a spring 52 with the pinion normally engagingthe gear 40;

but allowing its disengagement when the face 53 of a cam 54 (see 35..aots on the traw is deposited by hand or by a straw projection of thelever during; an entire Y i l n the cam, whereupon the spring heprojection. of the lever into the itch 515st the cam, and the pinion.e1. into contact witlrthe gear 4:0. From he understood that the cranks 3plunger 5 stand still while the its shal make one revolution, and t tiethe twine about t" e bales as fast as they have attained thepredetermined length.

In further explaining the above it will be observed. that the shaft 57operates two kuotting (.lfiVlCOS or knotters 58, mounted. near die rear01' the hopper, where they arc merely imlica'ied in the drawing but notillustrated. as to crmstructirm, since the lui tcr is the same as thewell known knottcrs wed in sell himling harvesters. Below the baliugchanlher is .journalml a rock-shall 5E}, rocked by its short arm (Tillpitmau (51 and pin 62 in the sprocket WllLOl 62, which is ecured on thesame shalt cam 51, or may even be made integral with the cam. (hi ihcrockshalft of} are also lixcd two longer arms 63 i ash a needle whosepoints when all; is rocked. ascend through an apcrtore 66 in the bottom.and in the top of the baling chamber, and carrying in its eye the twine67, extemliog from the twine ball holder 68 through the tension (ll-nice6i) and over the bale as indicated by dotted line 67", 67 to theknotting device, brings to the knotter the part of the twine to be tiedinto a knot with the part always remaining there, and as the knot istied thr needle descends, of course the two needles act in the samemanner, and the twines hang down from the knottcrs in the path of thenext bundle formed and are thereby placed over the bottom, top and oneend of the halo, the needles bringing them up over the other end.

The means by which the cam 54 is started and stopped will now'bedescribed. Below the crank chamber is ournaled a transverse shaft70,d.riven by its gear 71, which meshes at all times with the pinion41,- at the opposite end of said shaft is fixed a sprocket wheel 72,driving by a chain 73 a double-sprocket wheel 74 lined on a shaft 75, onwhose opposite end is guided by a feather key 7 6 a slidable frictionclutch. member 77, having an annular groove 78 engaged by a bell-cranklever '7 9, pivoted to a bracket 80 and operated by a rod 81 and crankor rocker arm 82 of a rock-shaft S3, journaled in an adjustable frameand having a trigger arm 85 depending downwardly through a slot 86 inthe top of the haling chamber (as best shown in Fig. 5), that when afinished bale is pushed by the next bale against the trigger the shaftwill rock and push the clulclumeinhcr 7? into frictional. contact withits meeting member,

which is formed on the inner side of the sprocket wheel 77", which isloose on its shaft and only turned when the friction. between. thecluiclmnembers becomds great enough to turn it. To make saidl'rictionmore promp-actmg, 1 lm on the shalt 83 an. arm 37 will a weight 88 onit, so that when the weighted arm falls from its vertical posilion abovethe shalt tollic front, as in full lines in l ig. 1 the clutch member 77will be thniuvu and held. into sullicient frictional contact to turn camlVhen the clutch member 77 thus operates the wheel 77, chain 89, wheel62 and cam 54, the lingers 90 on chaiu'Sl) will touch the rocker arm 91.of a rock-sluilt 92 iouri'ialed across the top of the baling chamber andhaving two other rocker-arms 93 (see l ig. 6), each of which isconnected by a link ill. to the adiaccut end ol' a horizontal rod 95,sliding loosely bclwveci'i pins 96 or any other suitable guidcs, andpro-- vided with two lateral cams UT, which act as wcdging cams to throwoutward l he supporl..

99, where the upper end of each prop normally engages a cap orprojection. loll, as to the left in Fig. but when disengaged there fromby the cam 97 ascends as in full line to the right. The lower ends olthose props are pivoted to segmental arms I01, lixcd to two l'oldiugleaves 102, hinged at-lU-E, and. supporting the-bale until it has actedon the trigger R5 and thus caused. the cams )7 to trip the leaves: inthe u' aumer and. by the means just described. soon as the leaves arereleased of lhe bale, the weights 10S restore them to the level position again.

In order to make long and short bales, the small frame 84. is providedwith long slots 104. for the screws H15 holding it, and the rods 81 and106 are provided with several holes for the crank '82 and. the pivot107, so that the trigger may be moved to 4 16*, 18" or 24, which marksin Fig. 1 mean bales, 14, 16, 1S and 24 ii'icbes long: the bales mayhowever be made of any other length, and. ol' any desired thickness,although about 6 by 8 inches thick and i l to 24 inches long will coverthe present requirement for fuel of this class.

The weighted arm 87 is restored to its nornial position, loaning nguiusta peg 109 and with. the trigger 85 in position to receive a push fromthe next bale; this .rr-istoriiig is oftected by the rod 106, pivoted tothe lower end of the weighted arm 87 and sliding in a bearing 110. Atthe front end. ol this rod is a plate 111 on which is pivoted at 1 1.2 abellcrank lover I 13, whose short arm is held by a spring 114 against apin .or stop H5, and the long arm is provided with a lateral wing 116standing normally in an oblique position to the rod. The lever 49 has alinger 117 which when moved by said lever from the full-line position tothc'dottod position in Fig. 1, simply causes th spring 114 to yield,.and when the spring 52 throws the lover from the dotted to the solidline position, the 1111-- ger 117 acts upon the rear side of the wing orincline 116 and pulls the rod 106 forward and the weighted arm occupiesthe position 8%.

To prevent the needles 6-1 from ascending while the plunger is in theirpath, I use the following means; the gear 41 has upon its outer side asegmental hook or guard 118, which when the crank 0 holds the plunger inthe path of the needles is in a position to engage a hook 119, pivotedat.120 to the lever 49, is guided in a fork 120 and is normally held b aspring 121 against a projection. 122 of the ever. By thisarrangement itobvious that as long as the plunger is in the way for the needles thehook 118 will hold lever 49 in the notch 56 of the cam 54, and when thelatter cam can thus not turn, the clutch member 77 cannot turn.w reel 77a but must slip on it for a moment until the plunger is sufficientlyretracted to let the needles pass to the knotters. he spring 121 makesentirely sure that the guard 118 shall never prevent the spripg 52 fromthrowing the lever 59 into the notch ofcam 54 as soon as the latter isina position to receive it. Of course only accidental turning of thegear 40 could cause the guard to resist b its outer side the'hook 119,but if it shou d'happen,

then the spring 12 will swing the hook 119 inward as soon as t 1e gear40 starts to turn. The hopper 7 and the guarding boards 7 at the sidesof the conveyer 24 are preferably detachable from the main frame. Thedroping chamber in which the shelves 102 are ocated is wider-than thebaling chamber so as to give the bales a chance to drop freely.

The rear end of the baling chamber proper,

which terminates at the vertical side slots 3 has said terminal ends ofits side planks contracted or sprung inward by a clamping device (bestshown in Fig. 7), consisting of two clamping blocks 127 and bolts 128passed thro h them close by the top and bottom of the dl iamber, andprovided with nuts 129, the turning of which will bring the embossmentsat the inner sides of the blocks in between the top and bottom plank ofthe chamber and force-the side planks toward each other.

Having thus described my invention, what I claim is 1. In abailing-press, the combination with a baling chamber and an automaticbinding device, of a pair of downwardly foldable normally level" shelvesarranged for the bale to slide upon as it is pushed out from the balingchamber, a trigger or trip in the path of the bale and ada ted to beoperated by the bale when it is ful y on to the shelves, and meanswhereby the trigger trips the shelves and dro s the bale, means forrestoring the she ves .to normal position automatically, and anautomatic conveyor below the shelves for removing the bales.
